Hello all, I am in desperate need of some help. I'm writing my last paper for my senior capstone in physics () and my experiment is Faraday Rotation. I CANNOT find a reference for the Verdet Constant of SF59 glass at 650nm (found V for many other wavelengths). I have searched for hours and hours, checked through 4 different CRC handbooks, and can't find a source to cite. Now, dozens of papers online have said that the Verdet Constant for SF59 is 23rad/Tm, but no actual sources. Please, if you have a link to a credible source (CRC, NIST, etc.) with that information it would be much appreciated. Not sure if this is the right place, but I thought here was better than the Quantum section since I'm not asking about anything rather just a constant. If it's in the wrong spot, let me know. Thanks!
